6:9 Idolatry is here placed between fornication and adultery, because they generally accompanied it. Nor the effeminate - Who live in an easy, indolent way; taking up no cross, enduring no hardship. But how is this? These good - natured, harmless people areranked with idolaters and sodomites! We may learn hence, that we are never secure from the greatest sins, till we guard against those which are thought the least; nor, indeed, till we think no sin is little, since every one is a step toward hell.

6:11 And such were some of you: but ye are washed - From those gross abominations; nay, and ye are inwardly sanctified; not before, but in consequence of, your being justified in the name - That is, by the merits, of the Lord Jesus, through which your sins are forgiven. And by the Spirit of our God - By whom ye are thus washed and sanctified.

6:12 All things - Which are lawful for you. Are lawful for me, but all things are not always expedient - Particularly when anything would offend my weak brother; or when it would enslave my own soul. For though all things are lawful for me, yet I will not be brought under the power of any - So as to be uneasy when I abstain from it; for, if so, then I am under the power of it.

6:13 As if he had said, I speak this chiefly with regard to meats; (and would to God all Christians would consider it!) particularly with regard to those offered to idols, and those forbidden in the Mosaic law. These, I grant, are all indifferent, and have their use, though it is only for a time: then meats, and the organs which receive them, will together moulder into dust. But the case is quite otherwise with fornication. This is not indifferent, but at all times evil.For the body is for the Lord - Designed only for his service.And the Lord, in an important sense, for the body - Being the Saviour of this, as well as of the soul; in proof of which God hath already raised him from the dead.

17:14  Mar 9:14; Luk 11:37.

17:15 He is lunatic - This word might with great propriety he used, though the case was mostly preternatural; as the evil spirit would undoubtedly take advantage of the influence which the changes of the moon have on the brain and nerves.

17:17 O unbelieving and perverse generation - Our Lord speaks principally this to his disciples. How long shall I be with you? - Before you steadfastly believe?

17:20 Because of your unbelief - Because in this particular they had not faith. If ye have faith as a grain of mustard seed - That is, the least measure of it. But it is certain, the faith which is here spoken of does not always imply saving faith. Many have had it who thereby cast out devils, and yet will at last have their portion with them. It is only a supernatural persuasion given a man, that God will work thus by him at that hour. Now, though I have all this faith so as to remove mountains, yet if I have not the faith which worketh by love, I am nothing. To remove mountains was a proverbial phrase among the Jews, andis still retained in their writings, to express a thing which is very difficult, and to appearance impossible. Mat 21:21; Luk 17:6.

17:21 This kind of devils - goeth not out but by prayer and fasting - What a testimony is here of the efficacy of fasting, when addedto fervent prayer! Some kinds of devils the apostles had cast out before this, without fasting.
